The present invention relates to improvements intransmission mechanisms for concrete' mixers, one object of the invention,

being the provision of a transmission mechanism between an oscillatory or swingingly' mounteddriven member and an axially rotatable driven member and a driving mechanism such as an explosion engine, whereby the selective driven members may be operated singly or'jointly, the axially rotatable driven member pon stit'uting a mixing drum while the tilting member constitutes the annular member which carries the mixing drum, the drum therefor being rotatable within the annular member and the annular view which will appear as the description member oscillatable upon its axis.

With the foregoing and other objects in proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made with.-

in the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is atop plan view of the complete mixer embodying the present invention. Fig. 2 is an end view thereof, parts of it being broken away to demonstrate the gearingthe explosion onginebeing omitte tail views of various parts of the mechas 1 Referringto the drawings, the numeral 1 Q designates the framework which is mounted upon wheels W so that the present device may be transported from place to place. The open rectangular frame 2 constitutes the supporting frame for themechanism, the

explosion engine E being mounted at the front thereof, as clearly illustrated in Fig.

with and connected to the crank shaft c carrying the fly wheel 3 of theengine. 'The opposite end of the shaft 4 is mounted in the bracket'bearing 5 and as the engine rotates,

the shaft 4 will be rotated. Mounted upon i the shaft 4 is a small pinion 6, which meshes with the large gear 7, said gear 7 being mounted for free rotation upon the shaft 8, which is journaled in parallel to the shaft 4:, said gear 7' being provided with one clutch member 9 for coaction with the spool 10 which is splined upon the shaft 8 for rotatlon therewith. By this means, when the clutch spool. 10 is operated by the lever 10' to engage the clutch 9, the gear 7 is made fast to the shaft 8 and thus the shaft '8 is rotated through the shaft 4: and gear 6. Also mounted upon the shaft 8 is a clutch spool 11, which is controlled by the lever 11 and is disposed to coiiperate with the clutch member 12 which in turn carries the small gear 13 disposed to engage the gear teeth 14:.

formed internally upon the segmental frame 15. This frame 15 is provided with the two arms 16 and 17, and with the shaftlS. This shaft 18 is disposed longitudinally of the frame, and is journaled for rotation in brackets 18', while the two arms 18 carry the filling hopper or scoop 19.

Keyed upon and rotatable with the shaft 4 is a beveled gear 20, which is disposed to mesh with and engage the beveled gear 21 carried by the mixing drum or chamber 22, the latter being open only at one end so that the chamber may be disposed to receive the load from the loading scoop at one side of the frame and tilted to deliver the mixed contents at the opposite side. The beveled gear 21 and the rim 24 provide a roller receiving space 25 so that the rollers 26 which encircle the mixing drum 22 will permit of the drum being properly rotated therein and within the roller carrying frame 29, which carries the sleeves 28 in which are mounted the stems 27 of the'rollers 26.

lnorderto impart rotation or oscillation to the mixer 22 from the receiving position to the emptying position, such emptying position being to the right, (Fig. 2), the gear 30 is attached to the trunnion frame 29, while the shaft 29 constitutes the bearing therefor at the opposite side. Meshing with the gear 30 is the worm gear 31 which is keyed upon and rotatable with the shaft 32, which in turn is journaled as illustrated in Fig. 2, so as to have the friction members 34 and 35 carriedby the manually controlled collar 33 to place one at a time in engagement with the member 36, and as the shaft 1 4: is rotated, the desired eseillation will be imparted to the cement mixing drum. When the members 84 and 35 are in neutral posi tion, the mixing chamber may be maintained in either position for receiving or emptying the load.

I prime mover embodying a drive shaft; a

tilting frame; a rotatable member journaled on the frame; an. actuating shaft disposed parallel to the drive shaft; an operative eon neetien between the shafts and including an element rotatable upon one shaft; clutch means for uniting the rotatable element with its shaft \vhereby the actuating shaft may be driven from the prime mover; intermeshing gears on the actuating shaft and the frame carried rotatable member whereby the frame carried member will be rotated when the actuating shaft is rotated; a third shaft disposed at right angles to the drive shaft and the actuating shaft; an opera 1V8 eonneetion between the third shaft and the f *ame whereby the frame "will he tilted the third shaft is rotated; gear Wheel fixed to the drive shaft and selective gears splined'to thethird shaft and adapted te eeact respeetively with the gear Wheel ef the table member;
